Hazards may exist within this equipment because it contains electrical and powerful moving components.
Only qualified service personnel should install or service this equipment. Untrained personnel can perform basic maintenance such as
maintaining filters.
Observe precautions marked in literature and on labels attached to unit. Follow all safety codes.

                                                                                !   WARNING
Disconnect main power switches to unit before performing service or maintenance. Electric shock can cause
personal injury or death.

response to the outdoors temperature 23°F to -22°F (-5°C to -30°C).
On a call for defrost, the supply air damper in the recirculation
module closes, exhaust fan is de-energized and the supply fan
continues to recirculate warm air through the heat recovery core
or energy recovery core. It is possible to extend the defrost times

Before proceeding with balancing, all windows, overhead doors and
walk-in doors should be closed and exhaust systems should be turned off.

Although the 6LC, 7000 and 12LC models have good efficiencies, the supply air could be colder than the ambient room air. It is possible to eliminate the discomfort
     associated with this temperature difference by installing an electric duct heater. This will temper the air before it is distributed throughout the building.
     The tables below gives the heating requirements at different temperatures and airflows.
